15 + 1; 14 + 2; 13 + 3; 12 + 4; 11 + 5; 10 + 6; 9 + 7; 8 + 8
3)The angle must equal 115. (alternate exterior angles are congruent, same in measure).
5)The missing angle equals 128. (corresponding angles are congruent, same in measure).
The given formula is

Therefore

Given:
C = $25,000
V = $12,000
t = 4.5 years
C/V = 0.48
1/t = 0.2222
Therefore

Answer: 15% (nearest integer)
Answer:
Test statistics = 2.29
P-value = 0.01101
Step-by-step explanation:
We are given that a survey conducted five years ago by the health center at a university showed that 18% of the students smoked at the time. This year a new survey was conducted on a random sample of 200 students from this university, and it was found that 50 of them smoke.
Let Null Hypothesis,
: p = 0.18 {means that the percentage of students who smoke has remained same at 18% over the last five years}
Alternate Hypothesis,
: p > 0.18 { means that the percentage of students who smoke has increased over the last five years}
The test statistics used here will be ;
T.S. =
~ N(0,1)
where,
= sample proportion of students = 50/200 = 0.25
n = sample size = 200
So, test statistics =
= 2.29
Now, P-value is given by = P(Z > 2.29) = 1 - P(Z <= 2.29)
= 1 - 0.98899 = 0.01101 or 1.101 %
Therefore, P-value of the test is 0.01101 .
